Oh man, if you like that paper do I have the list for you. We used this list while doing some literature review when we were doing research on HPs memristors <a href="http:&#x2F;&#x2F;webee.technion.ac.il&#x2F;people&#x2F;skva&#x2F;new_full_reference_list.htm" rel="nofollow">http:&#x2F;&#x2F;webee.technion.ac.il&#x2F;people&#x2F;skva&#x2F;new_full_reference_l...</a>. That covers a pretty wide range of topics related to memristors

There&#x27;s another similar such element - which has a somewhat confusingly similar name:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Memistor" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Memistor</a><p>It was developed by Bernard Widrow in 1960, whereas the memristor was envisioned and named in 1971 - but not found to actually exist until 2008.<p>The memistor was most &quot;famously&quot; used to develop a couple of artificial intelligence (neural network) systems, ADALINE and MADALINE:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ADALINE" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;ADALINE</a><p>Note that if you try to google &quot;memistor&quot;, you&#x27;ll maddeningly get suggestions and results for &quot;memristors&quot; instead - even when you tell google to show you only results for memistors only; this makes finding information about them online difficult. It&#x27;s best to add to your search &quot;adaline&quot;, &quot;madaline&quot;, and&#x2F;or &quot;widrow&quot;.<p>The main difference between the two devices are that the memistor is a three-terminal device, versus the memristor being a two-terminal device. You can think of the memistor as being a &quot;memory transistor&quot; vs the memristor as a &quot;memory resistor&quot;. This is gross simplification, of course.<p>One other interesting thing about ADALINE is how simple the memistors are to construct; you can effectively re-create ADALINE at home, as Widrow&#x27;s paper shows:<p><a href="http:&#x2F;&#x2F;www-isl.stanford.edu&#x2F;~widrow&#x2F;papers&#x2F;t1960anadaptive.pdf" rel="nofollow">http:&#x2F;&#x2F;www-isl.stanford.edu&#x2F;~widrow&#x2F;papers&#x2F;t1960anadaptive.p...</a><p>On the topic of memristors - they can be DIY&#x27;d as well:<p><a href="http:&#x2F;&#x2F;sparkbangbuzz.com&#x2F;memristor&#x2F;memristor.htm" rel="nofollow">http:&#x2F;&#x2F;sparkbangbuzz.com&#x2F;memristor&#x2F;memristor.htm</a><p>Finally - if you&#x27;re interested in this kind of thing (that is, implementing hardware analogs of brain functionality), google &quot;neuromorphic computing&quot;...

Fun fact: Leon Chua is Amy Chua&#x27;s (of Tiger Mom fame) father.

Anybody knows what happened to to HP&#x27;s &quot;memristor&quot;? Was it only vaporware?

Brains have the equivalent of memristors. Changing the value of the memristors gets harder the more charge it has. That is why spaced repetition as a learning method works as a memory technique.<p>When we sleep the brain organsizes and decides what to keep&#x2F;forget. Artificial intelligence probably needs to emulate sleep.

Ok, I get that capacitors and inductors are opposites, but I&#x27;ve yet to understand the significance of why the memristor is the opposite of a resistor... Chalk it up to my primitive knowledge of analog design.<p>Couldn&#x27;t theoretically there be a mempacitor and a memductor as well?

Here&#x27;s a nice talk about memristors:<p><a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=bKGhvKyjgLY" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=bKGhvKyjgLY</a>
